Good morning,
Yesterday, we received a quote for a photovoltaic system. Our construction of the single-family house will start in October 2023 and is expected to be ready for occupancy in September 2024.
We have an annual electricity consumption of about 3000 kWh for our household, plus an unknown amount for the air-to-water heat pump (Weishaupt Biblock).
Our roof is oriented exactly south with a 25° pitch (gable roof). According to the calculation in the quote, the entire south roof is fully covered with modules (20 units), and the north roof is also equipped with 5 modules.
Attached you will find the details of the quote. The price is €20,900 net with battery storage and €15,900 net without storage.
What do you think of the offer? From what I understand in the discussions here on the forum, it is advisable to skip the battery storage. That would bring the cost to just under €16,000, which is a bit over €1,600 per kWp. That seems relatively expensive, doesn’t it?
Thank you very much in advance for your help.
Best regards,
Elias

Raising the structure from 25 to 20 is an option you can take.Ah, like "decreasing the distance" then 😀RotorMotor schrieb:
Especially in winter, the low sun doesn’t reach the north-facing modules.Who’s talking about sun 😉 In winter, the sun often does not shine.
Every watt counts, and facing north actually doubles the yield!
KingJulien27 Jul 2022 12:03You are certainly right about the effort and the shading.
In PVSOL, I believe you can also mount panels on a raised structure.
I would always get two quotes: one for south-facing only, and one for both south and north-facing.
Then compare the cost difference in relation to the yield from the north-facing panels. That way, you know where you stand.
Self-sufficiency can be left out—that’s the buffer.

MDZ Hausbau27 Jul 2022 13:52The electricity price on the exchange has increased by 270 percent compared to last year's price as of today. This price increase is not even fully reflected in the current electricity prices yet.
Today, electricity costs 52.4 cents per kWh for the December contract. Quite extreme, I would say.
We are talking about net prices excluding VAT, grid fees, and all the other charges. So, the gross price could be around 1 euro per kWh.

However, this won’t stay this way, similar to gas prices.
If it does remain like this, there will be no industry left in our country in 2-3 years, because many pay these market prices directly.
Energy-intensive industries no longer make sense if energy costs ten times as much as it did in 2019.
Therefore, I would be cautious about relying on the extremely high prices of 2022 when purchasing photovoltaic systems or heat pumps at 2022 prices.
That said, I can understand why craftsmen charge these prices. Usually, a photovoltaic system ordered today will be installed sometime in early to mid-2023. How prices develop until then is unpredictable.
My company has already raised prices twice in 2022 and will adjust prices again in October. Customers who try to negotiate lower prices today risk having to pay extra money in mid-2023 to install their photovoltaic system.
And why should one agree to be pushed down on price? People are lining up; the demand for photovoltaic systems and heat pumps is enormous—there’s almost a sense of panic.

missing. The consumption might actually be calculated optimistically, BUT the electricity price at €0.35 is also optimistic... I hardly believe anyone will still be paying €0.35 in 10 years.
It’s always somewhat of a bet on the future. Obviously, the calculation becomes more profitable only with south-facing panels, but I’ve read so many times here in the forum that you should fully cover the north side as well, especially if you have an air-to-water heat pump. RotorMotor schrieb:
Everything is rather optimistic.
Taxes on feed-in are missing too.
Try calculating for south facing only. I need to dig up this thread again. You say that taxes on feed-in are still missing. Isn’t it the case that the feed-in tariff is net, and the grid operator applies VAT on these 7.62 cents (In my case, it’s that amount because I have 21 kWp, so not fully 8.2 cents) and pays me accordingly?

RotorMotor3 Sep 2022 17:02I think you are mixing up a few things.
Value-added tax applies to self-consumption (if it was deducted initially when setting up the system).
Income tax applies to the fed-in electricity (if the earnings are "large enough").
In my previous post, I was referring to income tax, which often significantly reduces the return.
